6N139-300E

Transistor, Photovoltaic Output Optoisolators Overview

The Broadcom Limited 6N139-300E is a high-speed optocoupler featuring a single channel with a Darlington phototransistor output. It provides 3750 Vrms isolation voltage and supports data rates up to 100 kb/s. The device utilizes a surface-mount 8-pin DIP (gull-wing) package. Key electrical parameters include a typical current transfer ratio of 400%, a forward voltage of approximately 1.7V, and an operating temperature range from -40°C to +85°C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• High-speed signal transmission capability for digital communication interfaces
• Enhanced electrical isolation via 3750 Vrms dielectric barrier
• Darlington output configuration providing high current gain

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial automation control systems requiring galvanic isolation
• Data acquisition modules with ground potential differences
• Power supply feedback loops for noise immunity

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix '300E' to confirm the surface-mount gull-wing package variant, as standard versions may differ in physical form factor. Ensure compliance with RoHS directives if required by the target assembly process. Cross-reference official datasheets for precise thermal dissipation limits under varying ambient conditions before finalizing component selection.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high common-mode transient immunity and moderate speed are required alongside significant isolation voltage. The Darlington output offers higher gain than standard phototransistors but exhibits slower switching speeds compared to logic-output variants. Evaluate circuit requirements against the 100 kb/s data rate limit to ensure adequate performance margins for the intended application bandwidth.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the 6N139 series of high-speed optocouplers manufactured by Broadcom Limited. The series is designed for applications demanding reliable signal transmission across isolated boundaries. The 300E suffix specifically denotes the surface-mount packaging option, distinguishing it from through-hole equivalents within the same functional family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include other 6N139 series variants such as 6N139-000E or 6N139-020E, provided the package type matches the design constraints. Verify that alternative components meet the same 3750 Vrms isolation rating and Darlington output characteristics.
